Knowledge of Wireless Networks

Knowledge of Wireless Networks

(W-LAN)

Wireless, or wireless is a communication between two or more points in which electromagnetic waves (rather than through cables) carry the signal of some or all parts of the track kamunikasi. Some models of wireless equipment include:

     *

       The mobile phone and beeper (pager) - which provides a connection for mobile applications and easy resume taken for perorazngan or business.

     *

       Global Positioning System (GPS) - gives the user convenience as drivers of cars, trucks, aircraft pilots, ship captains to ascertain the location of their position on the earth's surface.
     *

       Computer tools without wires - such as a cordless mouse and keyboard so membuqat freedom of movement for the user.
     *

       Cordless phone - a standard phone but can be used wirelessly. Unlike mobile phones, cordless phones have coverage limits and requires a terminal that is connected to the wired telephone network.
     *

       Remote control - cable TANAP be a tool that can control things such as toys or television and radio.
     *

       Two-way radio - including wAkie-talkie or service amateur radio (walkie-talkie-HT) should the communication.
     *

       Satellite television - provide the ability for viewers at almost all locations are hundreds more to choose different communication channels.
     *

       Wireless LAN - provides flexibility, and reliability separately for computer users in business and non-business.



Wireless LAN is a wireless network in which data transmission Lan (pemgiriman or receiving data) is done through the air via radio frequency technology, providing large segaian superiority and advantages of the old technology but are not limited to LAN media kable or wire.

Regulation LIGHT

Regulation LIGHT
In the performing arts, lighting is in production engineering discipline along with good performances, craft stage (stage craft) and other things that are as visual support a pergelarlan.dalam developments in Indonesian performing arts production techniques have not received sufficient attention even in education kesenianpun tidakada majors who opened the specialization of production techniques.
With the increasing number of performing arts festivals in various cities the need to package the show into something exciting and different from the presentation of another group, the need for an understanding of production techniques to grow. But the growth of the performing arts are often not in line with the development of the theater. Room acoustics, lighting and arrangement pentasnya techniques often do not meet the minimum requirements for a performance.
In a situation such as that of the workers behind the stage reverse order show a significant sesuau and got donations in perkebangan pertunjukun art.
Studies conducted by the backstage workers are generally done by the actors themselves or together with the group or if lucky enough to attend workshops organized by arts institutions that have pehatiandan concern over the development of the performing arts world.
A light stylists besides the study of the text, choreography and visual art that others should know about the technical aspects of the equipment will be media expression and to understand the character of this form of stage and auditorium. Comprehension of the text can be understood by studying the history of the genre and style of the show. (Sumarjo Yacob books, Asrul Sani, Rendra, PW, NR, KA, etc.). Understanding of engineering planning stage and drawing techniques can be aided by computer control (Beamlight, Write Light, Daslight, Corel, CAD, Vector Work, WYSWYG).
Textual studies
Learning the script plays, poetry, short stories and prose. The goal is to train the sensitivity to see the lines of the text, agile construct plot and found a variety changes susasana, space, thoughts of the characters and establish dramatiknya structure.
By studying the background of the author it will be found that the vision of the writer concerned. Because the core of the arrangement of the light is built atmosfere for leaders who are turned off stage. Of course in this case the discussions with the director and other artistic workers such as stylist sets, etc is a must. The decision is the director post.
STUDY stage and AUDITORIUM
Characters from highly dependent on the auditorium stage and each stage has a very specific aura. Generally it can be divided into 3 different forms, namely:
1. Proscenium stage
Shape the stage where the audience with pentasnya separated by the orchestra pit and the audience sees from one direction only. Pentasnya given frame as the four walls of the room opened. (Puppet People, Kethoprak)
1. Arena Stage.
Shape the stage where the stage and the audience are under one roof. The audience saw performances from various sides which are generally 3 sides. The variation is very much like a horseshoe, circular (theater in the round), etc..
1. Trust
Combined with a proscenium stage theater arena. (Sasono Langen Budoyo).
Of the many variations of the stage, which palik prosceniumlah much needed support equipment to make the presenters actually become the center of attention of the audience.
TATA STUDY OF LIGHT.
The main study of the arrangement of the light is natural and all its contents. Because of the arrangement of light on stage is the imitation of what happens in the universe is. From the source cahayanyadapatlah divided into two, namely:
a. Direct Light
The light coming from the sun with all the reflections.
a. Indirect light
The light coming from the moon with all sorts of reflections.
Application of the above sources of natural lighting into the following performances:
- Key Light
The main light coming from the lamps type profile, lekolite and ellipsoidale. Character sharp glow of light that can be made very sharp and spread due to the planno convex lens that can be adjusted the distance to the light source. Usually used to expose specific areas and special use.
- Fill Light
Fill light coming from the lamps fresnell and flood. Character soft light and evenly from the center to the edge, because the light source is broken down by sperikel lens, but the light can be concentrated or dispersed by adjusting the lens with light sources. Usually used to get the atmosphere by flushing the stage with warm colors and cool.
To achieve maximum results on lighting system, the lighting should have sufficient knowledge about the grid system and electrical installation sgala safety rules.
Distribution of light becomes an important part in the planning of lighting throughout the game in order to tercahayai, so that changes in motion and facial expressions can be observed by the audience well. See position on the stage, the lighting can be divided into:
- Front Light
The light coming from the front of the stage that aims to make the face can be seen from the audience. Light source and the object distance is quite far then required profile, lekollite, ellipsoidale that light can be controlled, because by using the dash light shutter proscenium wall can be removed
- Over Head
The light comes from overhead expose players to the goal from the top of the stage area. Areas for players to drop straight over head light player (downlight) although the risk of being more easily broken bulb by heat is not channeled due to the position. Because the distance is not too far away, type Fresnell and Plano Convex (PC) is an option. However, due to economic considerations PAR CAN be an alternative medium.
Down Light
Areas for players to drop straight over head cahay players, though risky bulb becomes more easily broken by heat that is not channeled due position. PC, Fresnell and Lekolite be an option, but PAR CAN Very Nerrow may be alternatives.
- Back Light
The light coming from behind the player who makes the top players to be brighter than the rest, so the player as if it does not stick to the backdrop. Fresnell and PAR Medium Can be chosen.
- Light Side
The light comes from the useful damping expose the left or right side of the player. This light is needed for major dance works ballet because a lot of movement and jumping leg lift.
- Cyclorama
A soft light from above (upper horizone) and from the stage floor (lower horizone) function is to provide the horizon and changes in mood. Flood and Striplight with different variations of choice.
After doing research on the needs of the desired artistic director and onstage to collect data that will be used for performances, rehearsal observe, measure the length changes from one scene to another then start work designing a light plot. (Plan stage, lighting template, Vector Work, CorelDraw, CAD, Daslight etc.)
Work the lighting (paper work) as follows:
Light Plot:
Placement of the lights in the form of images, type, no channel / dimmer, color and direction of light, distance.
Hook Up Channel:
The form lists that provide no information channel.
Instrument Schedule:
In the form of lists that contain information placement and lamp type.
Magic Sheet:
List form that informs the color, area, and no channel to make it easier when making the Cue Sheet.
Cue Sheet:
Form list which lists no channel, the intensity and duration of changes in each of each cue.
The implementation schedule is usually set staging preparation ole Stage Manager (SM), is usually the order is mounting set, the arrangement of light and sound arrangement. Often almost done simultaneously for a very short period of preparation. Cold hands and cheerfulness and firmness SM will make this situation easy.
Stages of the work done by the team of lighting after coordinating with SM or SM group of buildings yng concerned are as follows:
Installation:
Work hang lights according to type and position, post installation according chanell no choice.
Trim:
Placing the lamp (batten) at the desired height.
Channel List:
Checking if no channel is in conformity with the hook up.
Focusing:
Directs the light to the desired area once installed filter light.
Plotting:
Arrange lighting cue along with the cast and director that area, atmosphere, intensity according to the will of the director. In this process often occurs very exciting discussion process that takes a long time.
Dry Rehearsal:
Exercise all the necessary technical aspects in the show, change sets, change the lights and sound effects guided by the SM but without players. Often referred to as Technical Rehearsal.
Dress Rehearsal
Exercise complete all aspects of staging, the player with full makeup and fashion from start to ahkir. This rehearsal is often sold to the public at a cheaper price than the day the show, as well as to the families of the players and reporters to see how the audience response. Command conducted by BC and his crew who have been divided according responsibility given.

Explanation of IP

Explanation of IP
To set the address of each computer on a network, the IP address is used. IP Address is an address given to the network equipment can be identified by the computer to another computer. Thus, each computer can make the process of exchanging data / information, access the Internet, or access to a computer network using TCP / IP. IP Address is used to identify a network interface on the host of a machine (computer). IP addresses consist of a group of 32-bit binary number that is divided into 4 sections. Each section consists of 8 bits, which means it has a decimal value from 0 to 255. Every 8 bits are called octets.
IP addresses can be separated into two parts, the network ID and a host ID. Host ID serves to identify the host in a network. While the Network ID serves to identify a network from another network. This means that all hosts connected on the same network have the same network ID as well. Some of the early part of the bits of the IP address is the network ID or network number, while the rest is for the host. The dividing line between the network and the host is not fixed (constant), depending on the class of network that we use.
There are several classes of IP addresses used in the TCP / IP in a network, namely class A, class B, class C, class D and class E.
Class A, Class B, and Class C are three classes of addresses used on IP networks in general practice, IP Address Class D is used for multicasting, the use of the application jointly by a number of computer
IP Address Class E
In the E-class IP network address, the first 4 bits of the IP address is 1 1 1 1.IP address class E has a range between 240.0.0.0 - 254.255.255.255.IP Address class E is the class of the IP address that is "experimental" or trial . Experiments are prepared for the use of IP addresses in the future.
The first four bits are always set to binary 1111. The remaining 28 bits are used as an address that can be used to identify the host.
The standard defines an IPv4 network address Class E as a backup, which means that they should not be used on IP networks. Several research organizations use Class E addresses for experimental purposes. However, the node which tries to use the address on the Internet will not be able to communicate well.

meaning and function of utp cable

meaning and function of utp cable

To understand the function of UTP cable, the better we discuss the notion of time about what it stands for UTP or Unshielded twisted-pair. UTP cable is a type of cable is made of conducting material copper, have isolation from plastic and coated with an insulating material that can protect from fire and physical damage.

UTP cable consists of four pairs of complicated inter-core cable, each pair has a different color code. UTP cable has no protection from electromagnetic interference, but this type of cable is widely used because of the relatively low price and functions that it is in conformity with the standards expected.

UTP cable function is used as a wired network LAN (Local Area Network) on a computer network system, and the UTP cable typically has approximately 100 ohm impedance, and is divided into several categories based on ability as a conductor of the data.

In everyday use, UTP cable has been very well used as a wired computer networks such as the use of office space or in an enterprise network system. Regarding some of the weaknesses and shortcomings UTP cables that are not resistant to electromagnetic fields and collision damage to a hard object, it can still be overcome by installing a protective outer tube such as plastic.

understanding Computers

understanding Computers

Computers are tools used to process data in accordance with procedures that have been formulated. The word computer was originally used to describe people who perkerjaannya perform arithmetic calculations, with or without the tools, but the meaning of the word is then transferred to the machine itself. Origins, processing information almost exclusively related to arithmetical problems, but modern computers are used for many tasks unrelated to mathematics.

In this definition that there are tools such as slide relu, mechanical calculators types ranging from abacus and so on, until all contemporary electronic computers. The term better suited for a broad sense as "computer" is "that process information" or "information processing system."

Today, computers are becoming more sophisticated. However, before the computer is not small, sophisticated, cool and light as now. In the history of computers, there are 5 generations of computer history.

Computer parts

The computer consists of two major parts of software (software) and hardware (hardware)
hardware

     * The processor or CPU as the data processing unit
     * Memory RAM, a place to store temporary data
     * Hard drive, semi-permanent storage media
     * Input device, the medium used to enter data to be processed by the CPU, such as a mouse, keyboard, and tablet
     * The device output, the media used to display the output of CPU processing, such as monitors and printers

software

     * Operating System

Basic program on a computer that connects users with computer hardware. The operating system used is Linux, Windows, and Mac OS. Duties include operating systems (but not only) set of program execution on it, coordination of input, output, processing, memory, and software installation.

Adobe Premiere Pro 2.0

About Adobe Premiere Pro 2.0Adobe Premiere Pro 2.0 (APP) is a standard program that is widely used by the editors, are taking advantage of this program is the support for third party plug-in - her many and cool - cool, and it is fully integrated with Adobe After Effects (AAE) famous it, so it is like we are doing a project in premiere and takes effect-that is in efect AAE then we stayed at the AAE import our project.But keep in mind the success of the process is highly dependent import of resource that we use, in the format required AAE as a resource is the format of AVI, DV AVI format should be as another format such as MPEG 1 and MPEG 2 can not be read by the AAE, it is also possible AAE is so weakness.Plug in some of the famous giant red belongs to the Magic Bullet and Trapcodenya and many more can be seen on his website videocopilot. Premiere is a bit heavy program, the minimum required specs are dual core processor computer 2.0 G, core 2 duo all series recomended, RAM 1 G and 2 G recomended, VGA 128 add on PCI Express to preview and rendernya process faster.
Color Correction owned by the premiere of a very qualified, but I hardly use it because it is very heavy at the time of rendering, but the color correction we use is very suitable for the manufacture of clip - short clip for the music as it is usually required in the making of the video clip unnatural color system, depending on the theme carried in the video clip itself, such as the application of color-leaning blue, green, red or even black depending on our creativity and client demand, of course, but I think this color corection not well suited to the pursuit of natural images, should be a good natural images are obtained through the support of hardware when we record an image, use a good quality camera and good lighting system so that we get the resource files can be good at capturing. to capture the best image is in the morning and evening, for shooting in daylight to avoid shooting angles that direct sunlight.for titling itself provided a wide range of templates and template as a background titling some nice things I think we can use a little touch of the transition in order to make us more attractive titling.For the purposes of making VCD / DVD premiere version 2.0 already provides through Adobe Media Encoder encoder, we can even directly burn into ROM drive us straight from the premiere, but I did it rarely, better rendered first and burn using another program such as Nero or Ulead Video Studio. Fundamental weaknesses that exist in the premiere is not capturing the output MPEG1 or MPEG2 format, must be captured with DV format first, I understood why ga premiere party does not provide this facility.In the world of work as an editor, premiere master is absolutely necessary, because most homes - production houses and TV stations in addition to using the program AVID Express and Final Cut Pro course. However, for production purposes should be done at home using Ulead Media Studio Pro 8 or Sony Vegas because it interfaces easily and provide capture MPEG1 and 2.so first this post on premiere pro 2.0

blogger

Blogger or Blogspot is now called familiar among bloggers. This free blog service providers are large companies that compete with Wordpress so is arguably the number one free blog providers worldwide best-seller.

Blogger is actually a blog publishing system (blog publishing system) that was originally created by Pyra Labs on August 23, 1999 and is a dedicated blog-publishing tool first kaliyang intended to help popularize the format. In February 2003, due to its popularity, eventually Pyra Labs was acquired by Google. This acquisition memnyebabkan premium features that were previously charged, then turns free.

In 2004, Google introduced its new service Picasa, which is an application for organizing and editing digital photos. The service is then integrated in photo sharing utility Hello into Blogger, allowing a user of Blogger to post their pictures made ​​in your blog.

On May 9, 2004, Blogger redesign the main display, various changes were made in the Blogger by adding features such as web standards-compliant templates, individual archive pages for posts, comments and posting menggunankan email.

On 14 August 2006, Blogger launched its latest release in the beta with the code invader, along with the release version of Gold. This makes the migration of users to Google servers and is accompanied by the addition of several new features in it.

In December 2006, the latest version of Blogger is finally no longer in beta and in the month of May 2007, Blogger had actually moved to Google servers.

UTP cabling techniques RG-45

UTP cabling techniques RG-45
Unshielded Twisted Pair Wiring module using a Registered Jack (RJ), which is called RJ-45. Trick thing to understand is to make sure that we connect the right color on the pin RJ-45 the right time. There is some consensus that the sequence of the wiring, namely: 568A, 568B or 258A.

Everything is a consensus that explains which cable should go to which pin. The first thing to note that 8 cable pairs is defined as 4 pieces. And no matter which standard will be used, each pair is always the same basic color. Standards used for asia region is EIA / TIA 568 B, has the cable arrangement as follows:

The difference in the use of type crimpe:
* PC - Router / Hub / Switch: Straight* Hub - Router: Straight* PC - PC: Cross* Router-Router: Cross / Straight* Hub - Hub: CrossA. StraightKedua end of the cable is exactly the same order as in the picture.
The sequence is:
1.Putih - orange ... 2.Orange
3.Putih - green ... 4.Biru
5.Putih - blue ... 6.Hijau
7.Putih-brown ... 8.CoklatB. CrossoverSedangkan on making cable PC-to-PC, we menggunakna a different order on one cable ..
At the end of the cable "A" sequence is:
1.Putih - orange ... 2.Orange
3.Putih - green ... 4.Biru
5.Putih - blue ... 6.Hijau
7.Putih - chocolate ... 8.Coklat

At the end of the cable "B"
The sequence is:
1.Putih - green ... 2.Hijau
3.Putih - orange ... 4.Biru
5.Putih - blue ... 6.Orange
7.Putih - chocolate ... 8.Coklat
Or singkanya same way as making the order at the end of the cable "A" only sequence no.1 and no.2 no.3 changed to be no.6

3. Insert the cable ujung2 by pushing up stuck at the end of the inside of the RJ-45
4. Use the crimping tool to attach RJ-45 connectors. Enter the hole RG-45 (for the most part) and clips until you hear the sound "click".
5. Test cables with a cable tester. If the LED lights flash alternately eighth order, means it's connected properly.

Wiring in Computer Networking

Wiring in Computer Networking

In the installation of a computer network, it takes a useful medium for connecting multiple nodes such as computers, hubs, switches, routers, etc.. Media can be either wired or radio (wireless).

For media in the form of cable, which is like Coaxial Cable, Fiber Optic and Twisted Pair. And to be wireless like Bluetooth, Infrared, Wi-Fi, etc..

For now I will explain about the media cable used in computer networks.
Coaxial Cable

Coaxial cable is a cable is a cable that uses two conductors. The center of the coaxial cable in the form of wires in the cable core covered by a bulkhead and then dliliti again by webbed conductor wire. This cable has high bandwidth power

For coaxial cable, before the data is sent computer is sent, the data is first converted into an electrical signal. And then after the electrical signals reach the destination computer, the electrical signals are converted into digital signals again. This cable has a maximum distance along the 2000km installation.
Construction Coaxial Cable

The main conductor

Conductor cables should be made of solid copper cylindrical high conductivity seamless. For the diameter of the wires are not allowed to exceed 0.02 mm and 1.53 mm. As for the resistance of the conductor that is located in the (inner conductor) is 1/58 per 1 meter.

Isolation

Cable insulation made of homogeneous polyethylene and wrapped around the main conductor. For the nominal diameter of 0.97 mm and is also not allowed to exceed 0.05 mm.

Outer conductor

The conductor is made of copper tape with 0.25 mm thick with a maximum tolerance of 0.2 mm in the longitudinal position and overlapping slightly. For prisoners amounted to 1/52 per meter. At the top is wrapped in copper tape helikod with two layers of steel tape with 0.15 mm thick were used as pelindungelektromagnetik.

Hanger

Hanger here consists of seven steel wires wrapped bubbling with a size of 2 mm and a power of 3.010 kgf tensile strength.

Outer

Outer cables made of polyethylene mixed with 2% carbon black. For thick flat - flat wrappers are not allowed to exceed 2 mm and must not be less than 1.6 mm. As for the thickness of the hanger to the cable is 3.4 mm and with a height of 3 to 4.5 mm.
